Abstract/OtherAbstract:
2-months restriction of physical activity of dogs markedly reduced their capacity for prolonged running. The rate of exercise-induced Tre increases was significantly higher in the cage-confined dogs in comparison with controls. At the point of exhaustion blood glucose concentration and muscle glycogen content were similar in the control and cage-confined animals, in spite of the much shorter time of exercise until exhaustion in the latter. The exercise-induced increases in plasma FFA concentration were considerably lower in dogs after prolonged inactivity period in spite of the greater activation of the adrenergic system. It is concluded, that there are several factors which may contribute to the reduction of the ability of cage-confined dogs to perform prolonged physical exercise. The most important seems to be the diminished muscle glycogen content, modifications in exercise metabolism and exercise-induced hyperthermia.
